You are comparing paper cases with fiber wads to plastic shells and plastic wads. Is today's high antimony shot any harder than yesteryear's Lubaloy or nickel plated shot? Back in the day when Parker Bros. were building single barrel traps these were the ultimate trap load --
Of course gunsmiths can make trap shooters believe anything. It is well known that you can't get that Nth trap target without a Ljutic with a Stan Baker "big bore" barrel that is essentially the chamber all the way to the choke!!
